IMPROVEMENT lN ROLLER-SKATES.

Specification forming part of Letters Patent No. 191,542, dated June 5,1877 application filed April 16, 1877.

To all whom it may concern Be it known thatI, JOHN MINER, of Detroit, inthe county of Wayne and State of Michigan, have invented a new andvaluable Improvement in Roller-Skate; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation ofrthe same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings is a representation of a side elevation of myinvention. Fig. 2 is a section through the casting and heel and soleplate. Fig. 3 is a view showing the recess for the rubber spring.

This invention has relation to roller-skates; and its object and purposeare to construct a skate of the above character simple in its parts, andone that can be easily and readily governed by the skater in guiding orsteer ing himself in such direction as he may. think proper; and theinvention consists in the general construction of the parts, as will behereinafter described, and subsequently pointed out in the claims.

In the accompanying drawings, A represents the heel and sole plate,preferably of wood, and is formed upon its under side at both ends withinclines a, thereby allowing a greater extent of rocking motion, andenabling the skater to control the skate, and more readily andefl'ectually guide or steer it to the direction desired.

The rollers 19 are secured upon axles c of the castings B, said castingsbeing formed with journals d, byswhich they are secured to the underside of the sole and heel plate A by means of the eyes 6.

These castings B have two incline bearingplates, at d, and upon theunder side of the heel and sole plate A are recesses c, with a rib, f,said recesses receiving and holding a rubber spring, 9.

The two inclines upon the bearing-plates d d of the casting B admit ofthe skate having a free rocking motion either way, and

also act as stops and bearings, so that when brought in contact with theunder surface of the heel and sole plate, and against the inclines a,avery fir'msupport is obtained for the foot, and the rollers areprevented from coming in contact with the skate-wood.

The ribs f in the recesses e prevent the rubber springs g from extendingtoo far into the recesses, and thereby form a space each side of therib, by which the rubber has room to yield, and thus allow the inclinedplates d d to bear upon the under side of the wood and form a supportfor the plate A, while the spaces formed by the rib f admits of thespring 9 acting with greater force to throw back the casting from eitherright or left to a horizontal position.

The castings B may be formed in a single piece with the axles 0; but asthe axles should be of harder metal than that of which the castings arecomposed, I prefer to form the axle separate, with serrations it nearits center, and afterward place it in a suitable mold, and pour themetal which is to form the casting B around it, the roughened surface orserrations h preventing the axle from working loose.

Protecting-plates imay be secured to the under side of the plate A, toprevent that portion of the casting between the rubber springs fromcoming in contact with the wood, and thereby preserving it from wear.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

l. The castings B, formed with the laterally-inclined plates d d, incombination with the heel and sole plate A, with springs g,substantially as and for the purpose specified.

2. The combination, with the heel and sole plate A, formed at both endsand upon its under surface with inclines a, of the castings B, formedwith inclined plates 01 d and spring g, substantially as and for thepurpose set forth.

3. The heel and sole plate A, formed with recesses e and rib f, for thereception of the rubber spring 9, substantially as and for the purposedescribed.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

J GEN MINER.
